The journalist who led the Panama Papers investigation into corruption in Malta was killed. Daphne Caruana Galizia died on Monday afternoon when her car ... was destroyed by a powerful explosive device. A blogger whose posts often attracted more readers than the combined circulation of the country's newspapers, Caruana Galizia was recently described by the Politico website as a "one-woman WikiLeaks". Her most recent revelations pointed the finger at Malta's prime minister, Joseph Muscat, and two of his closest aides, connecting offshore companies linked to the three men with the sale of Maltese passports and payments from the government of Azerbaijan. Caruana Galizia filed a police report 15 days ago to say that she had been receiving death threats. The journalist posted her final blog on her Running Commentary website at 2.35pm on Monday, and the explosion ... was reported to police just after 3pm. Caruana Galizia ... set her sights on a wide range of targets, from banks facilitating money laundering to links between Malta's online gaming industry and the Mafia. Over the last two years, her reporting had largely focused on revelations from the Panama Papers, a cache of 11.5m documents leaked from the internal database of the world's fourth largest offshore law firm, Mossack Fonseca. Her family have filed a court application demanding a change of inquiring magistrate. Investigations into the case are being led by Consuelo Scerri Herrera. But Herrera had come under criticism by Galizia in her blog.
